sanitizer_atomic_clang.h
src/external/gpl3/gcc/lib: Makefile.sanitizer
Log Message:
gcc: lib*san: Enable built-in 64-bit atomic ops for !__HAVE_ATOMIC64_OPS
as already done for some mips platforms by upstream.
Now, libubsan (as well as libasan if platform itself is supported)
work on some ILP32 platforms.
Fix PR port-sparc/58352.
This may be slower than another possible fix where all 64-bit atomic
variables are replaced by 32-bit ones. But, it should still be better
than having relatively large diffs to upstream; sanitizers are not
enabled for normal use, anyway.
XXX
Note that filename confusion in upstream codes:
- "sanitizer_atomic_clang.h" is used also for GCC.
- "sanitizer_atomic_clang_mips.h" has no mips specific codes.
